Xilinx HBM2 Internals (2023)

I wonder if the author is doing anything to overclock the HBM here or if this is within the ratings of the Samsung HBM stacks. It's nice to be able to do this when you have a few cards, but if you are working with hundreds, it may not be practical to push the HBM this far without overvolting them a bit.

I'm not an expert on memory interfaces. How do you use HBM2's 1024-bit interface when you have ~200 I/O on a zynq ultrascale+? Are these psuedo-channels a SerDes for the HBM2 bus?

I feel like domains are pretty cheap so it would be easy to separate your fetishes from your work life.
